LIGHT-DEFLECTOR.

Specicaton of Letters Patent. Patentd Allg. 10, 1920.

Application led December 30, 1919. Serial No. 348,372.

To all whom t may concern Be it known that we, CARL S. BnowN and RALPH R. SHAFFER, citizens ot' the United States, and residents ot' Ashland, in the county of Ashland and State of Ohio, have invented a new and useful Light-Deflector, of which the following is a specification.

The object of our invention is to provide a novel light deecting device for deflecting the rays of light from headlights and adapted for use with all lights equipped with an electric lamp reflector; and to provide a device adapted to both take away the glare and to utilize all the light rays which are shed from a full round, or parabolic, reector. It is further our object to provide a device tor convenient attachment to a head light without requiring an alteration in the structure of the lamp, thereby making the cost of the device as small as possible. We attain the objects of our invention by the device illustrated in the accompanying drawings, in which- Figure 1 is a horizontal section through the casing and reflector ot a lamp equipped with our invention;

Fig. 2 is a front plan view oi? our device applied to a headlight;

Fig. 3 is a vertical longitudinal section through a lamp equipped with our invention; and

Fig. 4 is a detail perspective view of our reflecting device.

Like numerals designate like parts in each of the views.

Referring to the accompanying drawings there is illustrated a lamp casing 1 having a reflector 2. a lamp 3, and a front glass or lens 4. We provide a suitable bent metal strip 5 extending across the reiiector 2 in a downwardly inclined horizontal position as shown in Fig. 2. 'Suitably secured to the upturned edge portion 6 of strip 5, we provide a suitable felt strip 7, and interposed between the ends of strip 5 we provide suitable felt strips 8. Metal strip 5 is provided with an upper longitudinal bent portion 9 adapted to engage and hold a suitable light damping strip 10 of red mica or other suitable material. Formed on strip 5 are eX- tension strips 11 extending around the lamp bulb 3. We provide a wire 14 soldered to strip 5 and extending around the lower portion of the lamp casing adjacent the front glass or lens to support the reflector in place; and a wire 13 extending rearwardly `from strip 5 to the lamp bulb socket on which it rests as shown in Figs. 1 and 3 to secure the light refiector in stationary position within the headlight.

llfetal strip 5 is burnished on one side and is so'shaped as to deflect the light rays which the reflector would otherwise direct ahead so as to blind the vision of one facing the lamp. rThe light rays thus deflected back to the reflector are intensified thereby but are reflected from a point sufficiently low to come within the requirements oi certain municipal regulations. The up-turned edge 6 oi strip 5 gives the proper tension to hold the parts in place and as its edge is covered with a telt strip 7 glued to part 6, friction between it and the front glass or lens 4 is avoided- The wire 14 further holds the device securely in place. Wire 14 is so shaped as to fit into the folded portion 7 of strip 5, to which it is secured by pressing the felt tightly about the wire. Strip 5 is formed in an approximately S-shaped curve in cross section as illustrated in the drawings.

Extension strips 11 are of metal burnished on both sides and extend about the lamp bulb in order t0 further guard against glare and to produce as strong a light as possible at the height permitted.

The dimming strip 10 may be made of mica, glass, Celluloid or any other transparcnt substance so colored as to shed the intensified rays, mellowed by color, yet able to penetrate through smoke or fog.

It is within the contemplation of our invention to omit the half-moon mica strip, if desired. This strip being removably attached within the S-shaped folded portion 9, as shown in Fig. 3, the strip 10 being held at a rearwardly inclined angle relative to the front glass or lens, as illustrated in Fig. 3.

What we claim is:

1. In a light deflecting device for headlights, the combination of a metal strip eX- tending horizontally across the face of the front glass, said strip being disposed in a rearwardly slanting position and having an S-shapedfolded upper edge portion, a light dimming halt-moon strip removably held in a rearwardly slanting position in the aforesaid bent cdge portion `-of the metal strip, and means for securely supporting the device within the headlight.

2. In a device of the class described, a burnished metal strip, approximately S- shaped in cross section and extending horizontally across the face of a headlight, a strip of light dimming material removably attached to the upper edge portion of said strip, shock absorbing' strips interposed between said strips and adjacent portions of the lamp reflector and front glass, and wires secured to the strip and suitably shaped to securely but removably support the device within the headlight.

In a device of the class described the combination of a burnished metal strip approximately S-shaped in cross section, said strip beinp` positioned in rearwardly slanting` relation to the front glass of the headlight, and having a longitudinal upper edge grooved portion S-shaped in cross section the strip also having an 11p-turned front edge portion, rearward metal strip exten sions engaging about the lamp bulb and to deflect the rays of light to the lower portion of the lamp reflector', a strip of light dimminv material mounted on the S-shaped upper edge of the metal strip and adapted to dim the light in the upper halt` ot the lamp, and wires attached to the bent portions of the metal strip and shaped to engage suitable portions ot' the lamp to removably but firmly hold the device in the proper position within the lamp casing, substantially as illustrated.
